slaps notation
An informed student is a better student, and this site -good for us- is all about it
Beeing everithing scientific and carefully thought in your method your omission of the slaps notation must have clear didactic reason.
I figured out you did so to make us student work on our listening and ear training.
But there must be more about it, on the one hand I can immagine other ways to devolpe ear training, on the other for beginners would make the whole difference to be able to imitate faithfully a Pro right from the beginning in order to eventually devolpe them own "feeling" for the ornamentation-color (while by istance I do miss none of the pulls which are notated, is not so for the slaps which often are very very soft and hard to "discover")
Speaking about me, knowing which abilityes we are supposed to devolpe becouse of that notation omission will make more meaningfull and sofor more focused the training
There are 100 degrees (1% to 100%) of how much of a slap can be used (in other words how much of a chord precedes the single note)... impossible to notate. Rule of thumb... if YOU can hear a slap, use a slap... if YOU think a slap sounds good, use a slap.
